摘要
作为移动网络解决热点覆盖和数据分流的有效途径,Small Cell在实际部署时仍面临着小区间干扰、移动性管理、回程承载、负荷均衡、维护和优化等难题。为有效克服和优化这些问题,在其演进技术Small Cell Enhancement中,分别从提高频谱效率和协作能力2个方向在关键的物理层提出了一系列潜在技术方案,从而进一步提高系统容量、均衡系统负载,同时更好地兼容现有LTE/LTE-A网络体系。
As an effective way to tackle hotspot coverage and data traffic offioading in mobile networks, Small Cell is still facing some difficulties in practical deployment, such as inter-cell interference, mobility management, backhaut traffic, load balancing, maintenance and optimization. In order to effectively overcome and optimize these problems, Small Cell Enhancement, which is the evolution technology of Small Cell, presents a series of potential technical solutions in improving spectrum efficiency and collaborative capability on the physical layer, leading to further increasing system capacity, balancing system load and having better compatibility with existingLTE/LTE-A system.
